Front and back side synchronous printing equipment

Abstract

The invention discloses front and back synchronous printing equipment, and belongs to the field of printing equipment. The front and back side synchronous printing equipment comprises a heat preservation shell, a printing cavity, a pair of printing parts, a supply part, a heat preservation layer and a pair of ink coatings. The printing cavity is formed in the heat preservation shell, and the two sides of the printing cavity in the horizontal direction penetrate through the heat preservation shell to form a rectangular through hole. The printing parts are symmetrically arranged on the two sides of the printing cavity and rotationally connected with the heat preservation shell, each printing part comprises a printing wheel and a printing shaft which are fixedly connected, the two ends of each printing wheel are rotationally connected with the inner wall of the printing cavity, and the two ends of each printing shaft penetrate through the printing cavity, extend out of the heat preservation shell and are connected with external driving equipment. Through action driving of the elastic sealing piece in the supply part, external air enters the storage cavity, so that ink in the storage cavity is in a flowing state all the time, and the condition that the ink is dry due to long-time stacking of the ink is avoided.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a synchronous printing equipment on both sides of the front and back. Background technique [0002] Machines that print text and images. Modern printing machines are generally composed of plates, inking, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first, the text and images to be printed are made into a printing plate, installed on the printing machine, and then the ink is applied to the place with the text and image on the printing plate manually or by the printing machine, and then directly or indirectly transferred. Printing onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass and ceramics to reproduce the same print as the printing plate. The invention and development of the printing press played an important role in the spread of human civilization and culture. [0003] In traditional...

Problems solved by technology

[0004] The purpose of the present invention is to provide a synchronous printing equipment on both sides of the front and back, to solve the problem that in the traditional printing machine proposed in the above-mentioned background technology, the ink will dry out after being left for a long time, and at the same time, when the temperature of the printing part changes too much , It will also cause the ink to dry on the printing roller, which will affect the printing quality. At the same time, if the ink on the surface of the printed material is not completely dry, the subsequent operation will damage the printing surface, and it will also contaminate the ink on other equipment.
